Movistar Yamaha rider Jorge Lorenzo conceded he does not care about this year's MotoGP world championship as he battles through a slump in form. 

The defending world champion started the season brightly, winning three of the first six races along with two second-place finishes. 

However, in the six races since, the Spaniard has managed just one finish inside the top seven, with two race weekends yielding no points at all.

The slump has seen him fall drastically behind in the title standings, with Repsol Honda's championship-leader Marc Marquez now 64 points ahead of third-placed Lorenzo.

Despite there still being 150 points up for grabs, Lorenzo said his focus for the coming races is on regaining his pace, rather than fighting for the title.

"I don't care about the championship because we are not competitive, we are losing a lot of points," Lorenzo said.

"Always somehow, always happens something for us to lose the points in the last [few] races.

"Let's see at Misano - in the dry we're okay to be one of the fastest, to fight for victory. And if it rains, to try to make another step forward."
